In the embodiment illustrated inthe drawing the'invention is shown as incorporated ina ,displaycase refrigerator having the'dis`- play case centrally located and the refrigerating chambers at eachv end, although it will, of course, be understood that thel features of the invention may be embodied in other structure. vThe refrigerant-ing. chambers are of duplicate construction and in the description of one it will be understood that it applies also to the other refrigerating chamber. The casein which the structure is 'embodied COmpI'iSes generally a rectangularv box having a bottomfwall 1, end Walls 2, a-

'Y VIntermediate the'walls 2O and 22 aredownwardly inclined baffle walls y 24:. The wall 19 has a series of perforation's n frigerant7 rpreferably inthe nforinof ice and or openings 25 that communicate vthe outer chamber around thewalls 19 and 21 with the Y V.space between. the walls 20-22-k-28land 24. l

Itwill bel observed that thel arrangement of the baffle walls 'described forms two'supplel'mental chambers on each side of thewalls 21 and between` said walls 21 andthe respective back fand front walls 13, so that when the refrigerant container isfilled with -the resalt and said compartments defined by the walls 13, '21, 22,16 and 19 are also filled. withl the refrigerantthere will be a refrigerating area near the top of the case formedby 'the wallsof said supplemental refrigerant compartments which deflect cool currents ldownwardly 'toward the center of the case y and; at an elevation substantially above the yleottjomfof the case, thus providing a `circulation ofwcoolcurrents across the top ofthe display compartment lof the refrigerator. It will also-be noted that the walls 24 provide foraftransverse distribution of cooling currents of air substantially intermediate ofthe top and bottom of the case andv entirely K. across the same. i

When the ice inthe refrigerant containers melts the brine will flow through the perforations 25 onto the wall 22 anda quantity ywilljbe trapped within the compartment be@ y tween said" supplemental refrigerant compartments, providing for maintaining a part of the refrigerating material. near the top yof the case. It will be understood also that a quantity of the refrigerant,will remain in f tliesuppleinental refrigerant compartments y between the walls V13, and 21.V Inasmuch as the wall 19, by means of the baffle walls 23 and 24, is within theY infiuence of the circulating area of the display compartment of fthe refrigerator, there will be continued circulation across the baiile walls carrying tothe interior of the case the cool currents ofair and maintaining asubstantially uniform 'temperature both inf the upper and in the lower strata of the display section of the i refrigerator.

' In order to` obtain the'maXiiiiuni eect from the refrigerating liquidI after it has -ineltetL that portion thereof .thatpasses onto over the dripA pan. v

The chamber formed by the walls 21 and 22 mayl be drained onto ithe upper plate 2i by a pet cock or valve 29 of any suitable` kind. .The lower chambergis drained through apet cock or valve 30 into a trough 31 that inclines forwardly and Vdischarges into a pipe 32 havingA an inwardly turned end 33 i' likewise discharging into the drip pan.

In Fig. 7 is a detail View of the preferred form of connection'betweenthe troughs 26 and 31 and -their respective vdischarge pipes 27 and 32. This connection comprises a tube 34; vertically disposed in the troughs, the

lower rend of the tube extendingabove av slot 35 formed in the upper wall of the disycharge pipes. The drip pan into which the pipes 27 and 32 discharge comprises a rectangular container 36 supported onr'le'gs 37V the bottom wall of the case substantially at the. center thereof. In order to increase the refrigerating effect of the drip panit is made with a central open flue 88. The drip pan has a vertically disposed `drainpipe 39 that discharges into a trap 40 formed in the bottom wall of the refrigerator case which is drained by a discharge pipe .111. f

It ywill thus be seenthat the construction described providesfor circulating from the refrigerant containersv lcooling currents of air at different elevations in the refrigerator case. It will also be seen that the construction provides means for distributing the re- 'frigeraiitrk throughout ythe case sot'that vthe.

cooling effect of the refrigerant,'not only in fthefform of ice and salt but as well, after the ice has meltedand the brine formed, is utilized in cooling` in distributed areas the entire case. It will be noted also vin connecn ICU tion with the drain arrangements for the refrigerant containers that the drip Vis distributed over eiposed surfaces of the bailie plates so that theywill be kept free from frost and so that the passage ways and openings between the baffle plateswill be kept .from clogging by the flow of the drip therethrough.
